Manufacturer description

The GuanTing Universal AC Adapter solves the drawer-full-of-orphaned-power-bricks problem with one 12V supply and 11 interchangeable DC plug tips. It accepts AC100V-240V 50/60Hz input and outputs DC12V at up to 2A, for 24W maximum power. Because it steps down cleanly to lower draws, the same unit runs devices rated 1.5A, 1A, 800mA, 500mA, 400mA, 200mA or 100mA, covering the 20W, 18W, 15W, 10W, 8W and 5W tiers too. The default barrel connector is the common 5.5mm x 2.1mm size with inner positive / outer negative polarity, matching most DC12V gear: LED strip lights, WiFi routers, ADSL modems…
